gpgme and delphi/pascal ?

[Philip]

Hi
I hope that this is the right place to ask.  Apologies if not.
These days I'm becoming a half decent amateur Lazarus/Freepascal
programmer, but I've not been able to read/write pgp encrypted files in
a pascal program.
The way to go according to the documentation seems to be to use gpgme,
which is fine if you are a C programmer, but I'm not and probably never
will be.
The only thing I can find is this
http://www.gnu-pascal.de/contrib/nicola/gpgme.pas
which seems to be a pascal unit which wraps up static linking of gpgme C
libraries, but it's not something I've done before, and I can't figure
it out.
Is there anyone here who has done before what I'm trying to achieve?
thanks, Philip
